I got so many DMs on my Instagram about lighting 一 which light shaper I use most commonly, what ISO I used on a particular photo, whether I use rim light, etc. Here are the answers to all of these questions.
The first flexible photographic roll film was marketed by George Eastman in 1885, but this original “film” was actually a coating on a paper base. As part of the processing, the image-bearing layer was stripped from the paper and transferred to a hardened gelatin support. The first transparent plastic roll film followed in 1889. It was made from highly flammable nitrocellulose (“celluloid”), now usually called “nitrate film”.
Although cellulose acetate or “safety film” had been introduced by Kodak in 1908, at first it found only a few special applications as an alternative to the hazardous nitrate film, which had the advantages of being considerably tougher, slightly more transparent, and cheaper. The changeover was not completed for X-ray films until 1933, and although safety film was always used for 16 mm and 8 mm home movies, nitrate film remained standard for theatrical 35 mm motion pictures until it was finally discontinued in 1951.
Films remained the dominant form of photography until the early 21st century when advances in digital photography drew consumers to digital formats.[25] Although modern photography is dominated by digital users, film continues to be used by enthusiasts and professional photographers. The distinctive “look” of film based photographs compared to digital images is likely due to a combination of factors, including:
- differences in spectral and tonal sensitivity (S-shaped density-to-exposure (H&D curve) with film vs. linear response curve for digital CCD sensors)
- resolution and
- continuity of tone.
